Color-changing and multi-colored electroluminescent cable

Abstract

The present invention relates to an electroluminescent light source. In particular, it relates to an multi-colored electroluminescent cable capable of changing colors, which comprises: a group of electroluminescent filaments which consist of a plurality of electroluminescent filaments of different colors and are insulated from each other, helically wound on the outer side of the axis; a transparent and flexible polymer casing tube disposed on the outer side of the group of electroluminescent filaments. The advantage of the present invention is low in power consumption, simple in structure, convenient for use, and has relatively long service life. The filament can be bent into a plurality of geometrical shapes as consumers demand, and it is beautiful and appealing. Besides, being extraordinarily extensive in its scope of application, the present invention can be used for external and internal housing and automobile decoration, and for external decoration for the purpose of advertisement, in entertainment places, and for toys, art and handicraft products and electric and electronic equipment.

AI Technical Summary

Benefits of technology

[0006]The objects of the present invention is to provide an electroluminescent cable, low in electricity consumption, convenient to use and capable of changing colors of the light with the changing of inputted information.

[0027]The color of said polymer casing tube disposed on the outmost layer of the cable is selected as customers demand and the casing tube has the function of protecting the cable.

[0034]The preferred thickness of said three coats of the present invention is the result of a lot of experiments made by the present inventor, and has overcome the drawbacks of the electroluminescent filament of the prior art. The present inventor has concluded from much experimentation that where the input power supply is of an equivalent parameter, the thickness of the medium insulating layer and light emitting layer has a direct effect on the light emission and bend resistance of the light-emitting filament. If the thickness exceeds 60 μm, the light emitted by the light-emitting filament will be dimmer. More importantly, when the light-emitting filament bends, the internal organization, under the impact of the internal bending force, is broken after being increasingly compressed along with the decreasing of the diameter of the bending, which would result in short circuit of the light-emitting filament or break the medium insulating player and the light emitting layer, thus disabling the light emission or causing partial non-light-emission of the light emitting filament.

Problems solved by technology

The conventional cable-like light emitting device mainly comprises: Neo light, with fragile glass outer layer, dangerous factors of high voltage and high frequency and incapability of being readily shaped, has the drawbacks of high power consumption and high cost for manufacture and maintenance.

The colored incandescent light using filament to emit incandescent light and colored tube to achieve colored light effect consists of a plurality of small incandescent bulb or light emitting diode(LED); This kind of color tube is of substantial diameter and its diameter of lattice light filament is 10 mm or more, and it is power-consuming, with its freedom of shaping being restricted by the large diameter and rigidity.

Moreover, the further drawbacks of said two devices lie in low efficiency in light emission, proneness to conductive wire damage and likelihood to cause fatal accidents when used in rainy weather.

Still another electroluminescent light source also has its deficiency.

The process is complex, and because transparent filler does not have a long, effective conductivity such that this kind of light source is apt to lose its function, the light emission can not last long, nor can the light be emitted evenly.
